CORRUGATED METALLIC OULVERT.

Specification of Letters Patent.

Patented March 9, 1909.

Application filed June 10, 1903. Serial Nb. 437,629.

To all wiwm'it may concern:

Be it known that I, HOWARD MALLERY, a

I citizen of the United States, residing at Owego, -county of Tioga, andState oiNew York, have invented a certain new and useful Improvement inCorrugated Metallic Culverts, of tion. V I My invention relates tonewand useful which the following is aspecifica- "improvements incorrugated metallic cul:

verts',-and has for its object to provide an exceedingly simple andeiiective device of this character which may be made'up of anumber ofsections out of separate sheets of, metal, these" sheets beingcorrugated and curved, to-these sections are riveted or bolted a-s'moothbottom plate, which acts as a bottom for the-culvertand also as aclosure.

With these ends in view this invention con sists inthe details ofconstruction and com-. bination of el ements "hereinafter set forth andthen specificallydesi nated by the claim.

In order that'those s illed in-the art to which this inventionap'pertainsmayunderstandhow to make and.use. the same, I will de. "Jribeits construction in detail referring by letter to the accompanyingdrawing form-' ing a part of this specification, in which- Figure 1;, isa side elevation of a numberof sections-which go to make up the-culvert,fastened, together. Fig; 2, a section at the line @XX of Fig; 1.

I In carrying out my invention as here enibodied, Airepresents a numberof sections Whichare made up of corrugated sheet metal so curved as toform the arc of the circle, thus leavin an opening B between the ends ofthese I tee, which when in position will be in t e bottom of the culvert.

These sections A are held together by rivetsor bolts C as used in allordinary iron Works.

D indicates a bottom. or closure plate, the length of which is equalt'oa number of the sections A and this is placed over the opening B andsecured to the sections A by rivets or bolts, the ends of the sections Aare then hammered fiat against the closure or bottom plate D or aplastic material may be used-t0 close the openings formed by thecorrugations resting against the bottom or closure plate for preventingwater or other substances from leaking out and this bottom orclosureplate D being smoothforms a bottom over which Water or solidsubstances contained in'the Water may readily run. This preventstheculvert-from becoming choked or stopped up.

Of course I the exact details of constructionhere shown,

- as these may be varied within certain limits without departing fromthe spirit of my invention.

' Havingthus fully described my invention what I claim as new and usefulis a In a metallic culvert comprising a-number of currugatedsheet metalplates so bent as to form-an arc of a circle thus leaving an opening atthe bottom thereof, smooth bottom or closure plates bent to form theother are of the circle, and rivets for securing said bottom platesover. the opening left between the edges of the corrugated plates, asshown and described. a
